There are different types of melanoma:
(1) 70% of all cases of melanoma belong to the type called superficial spreading melanoma. They occur most commonly the legs of women and the back of men between the ages of 30 and 50. These are usually flat and irregular in shape and colour, with different shades of black and brown.
(2) Nodular melanomas begin as deeper, blue-black to purplish lumps. They evolve fast and are more likely spread.
(3) Lentigo maligna melanoma usually occurs in the elderly. Sun-damaged skin on the face, neck, and arms is most susceptible to this cancer. It takes years to evolve.
(4) The least common form of melanoma called acral lentiginous melanoma.
